2 Claims.

This invention relates to a method of connecting a link bead chain tothe louver clips of a blind.

Another object is to provide a blind unit equipped with manuallyoperable, flexible means for supporting the louvers in spaced relationin their various positions of angular adjustment.

A further object still is to provide a bead chain and clip attachmentfor supporting the louvers in uniform spaced apart relation as well asmeans for retaining said louver-s in set adjusted position.

With the above and other objects in View, the present invention consistsin the combination and arrangement of parts, hereinafter more fullydescribed, illustrated in the accompanying draw- A clip I8 is welded orotherwise secured to each louver 13 at a point spaced equi-distant from.

the ends thereof, and projects beyond the front edge of the louver, anopening!!! beingprovided in the projecting section of said clip, and isof a size to accommodate and permit free passage ing, and moreparticularly pointed out in the appended claims, it being understoodthat changes may be made in the form, size, proportion, and minordetails of construction, without departing from the spirit, orsacrificing any of the advantages of the invention.

In the drawing:

Fig. 1 is a front elevational view of the blind unit equipped with alink bead chain,

Fig. 2 is an enlarged part sectional edge elevational view taken on theline 2-2 of Fig. 1,

Fig. 3 is a detail plan elevational View of one of the louvers showingthe clip which engages the link bead chain,

Fig. 4 is an enlarged, transverse sectional view taken on the line 4-4of Fig. 5, the broken lines illustrating the clip prior to the bendingoperation,

Fig. 5 is a fragmentary, top plan View of one of the louvers, and,

Fig, 6 is an enlarged, transverse sectional view of the blind unit,

Referring now more particularly to the drawing in which I have shown apreferred embodiment of my invention, the numeral 8 indicates a blindframe mounted in a window or door opening 9, the flanges 1c and ii ofsaid frame engaging the marginal edges or the opening in which it ismounted. A glass panel I2 normally forms a closure for the opening 9 inthe usual manner, and a Z-s-haped bar X provides for securing the glasspane.- in position.

A plurality of louver members 43 are pivotally mountedin openings i4provided in the side bars of the frame 8, each louver being formed froma metal strip iii, the edges of which are turned as at It to reinforceand stiffen the structure, the inner turned edges projecting beyond theend of the main body of the louver and forming pivot extensions 5?adapted to be mounted in the openings Hi provided in the side bars ofthe frame, so that said louvers may freely pivot therein, these louversbeing assembled in the side bars of the frame prior to the assemblingand Wilding of the frame proper.

of a bead chain 28 therethrough, the beads 2| of said chain being ofcertain predetermined diameter.

After the louvers have been mounted in the frame and the bead chainthreaded through the clips 18, these clips are then bent downwardly asindicated at 22, the bend being parallel to the edge or the louvers andbisecting the opening in the clip, thereby constricting the width of theopenings !9 transversely to the bend sufficiently to prevent passage ofthe beads 2 i.

A clip 23 is secured to the upper bar of the frame 5 and is slit as at24 to accommodate the bead chain links, so that the louvers may be setatany desired position of angular adjustment. Stationary skirts 25 and26 respectively, are

' provided at the upper and lower edges of the frame as shown andeliminate light streaks when the louvers are in closed position, theupper edge of the top louver overlapping the upper skirt 25, and thelower edge of the lowest louver l3 overlapping the upper edge of thelower skirt 25,

To adjust it is merely necessary to grasp the upper end of the operatingchain to swingthe louvers about their pivots ll untilsaid louvers are inthe desired position of angular adjustment, after which the chain ishooked on the clip 23 to hold the louvers in set position.

From the foregoing description, it will be obvious that I have perfecteda very simple, attractive, and economical blind unit for openings of allkinds.

WhatIclaim is: 1. The method of connecting a flexible linked bead chainformed with links of smaller crosssectional diameter than the beads to alouver clip provided with an opening therein, which consists inthreading the chain through the clip opening and then bending said clipto distort the said opening sufiiciently to prevent passage of the chainbeads.

2. The method of connecting a linked bead chain formed with links ofsmaller cross-section'al diameter than the beads to a louver clip.

provided with an opening of a size to permit passage of the bead chain,which consists in first threading the chain through said opening, and

width of the opening transversely to the bend suificiently to preventpassage of the beads through the openings in the clips.
